Northern lights over Norwegian Lapland
This stunning time-lapse video of the northern lights was filmed over Birtavarre in Troms, north Norway. The northern lights, or aurora borealis, are caused by electrically charged solar particles reaching Earth. The phenomenon was stronger than usual this week - even visible in the British Isles - due to a large ejection of solar particles on Sunday
